Method, System, and Apparatus for Adjacent-Symbol Error Correction and Detection Code

1. A method comprising: generating a set of m bits, wherein m is an integer, of a first symbol and a set of m bits of a second symbol from a first set of data for transmission over a channel to a memory during a first clock phase; generating a set of n bits, wherein n is an integer, of the first symbol and a set of n bits of the second symbol from a second set of data over a channel to the memory during a second clock phase; receiving a codeword from the memory in response to the first set and second set of data; generating a syndrome based on the codeword; detecting whether an error exists based on the syndrome; and classifying the error if it exists, wherein existence of an error is to be determined based on a syndrome and wherein a single device error is to be classified in response to a determination of a weight of a plurality of error values.

2. The method of claim 1 wherein the first and second set of data are stored in the memory.

3. The method of claim 2 wherein the memory is a Double Data Rate (DDR) memory.

4. The method of claim 1 wherein both m and n are four bits and constitute a nibble.

5. The method of claim 1 wherein the codeword is an adjacent symbol codeword which comprises an adjacent formation of the first and second symbol.

6. The method of claim 1 further comprising isolating a common mode error across the m and n bits of the first and second symbol.
